How to get bloodwork done under 18?

[yahflex]

How can I get baseline bloodwork done if I'm under 18? Most places say I need to bring a parent but I obviously don't want to make my parents suspicious as to why i'm getting bloods. I guess plan B would be to use a mail in test but I heard those arent really accurate.

would be better to just do the mail in test, such as rythm. It's been pretty accurate for me whenever I get bloods.
